Honeywell Wi-Fi Smart Thermostat RTH9580WF

My second thermostat.
I have this same model thermostat at home and like it because it’s easy to read and program so I bought one for my cabin.

Easy to ise
We like Honeywell thermostat and we bought 9 pieces from different sellers to install in each room in the house. We would like to say that we are quite happy with it so far. It is easy to use and to control from your iPhone. Now we can control our home temps while we are away.

Half-baked
The idea behind this is thermostat is quite good. However, the execution is poor, and it seems that the device was rushed to market. If you need to access your thermostat remotely, there are less expensive solutions available that do as much as this does, as well as more — even from Honeywell.The thermostat looks very nice, and it’s much smaller than you might expect. That’s a plus. However, the large colorful is all but useless, as it only shows basic information and menus on it — the advertised “5-day forecast” is **NOT** available on the thermostat screen, but only in the smart-phone app. It doesn’t even give the daily forecast, but only the current conditions. If you want to plan your day, you’ll need to pull out your smartphone, find the app, sign in and tap (or just use a different app). No, this isn’t a deal-breaker, but it calls into question why anyone would spend that much money on a touchscreen thermostat if the real estate on the screen isn’t utilized by the software.Another plus is the option to schedule the fan to recirculate rather than just the ON/AUTO options other thermostats offer. But once again, Honeywell missed out on making this feature great by providing no additional settings or adjustments. It might be better to circulate air more often when the outside temperature is higher during the day — but again, there are no options to adjust that.As far as thermostat control goes, it’s a bit sluggish, but works. The “temporary hold” options are a bit clunky, and could use separate controls for hour and minutes. Changing it by several hours is a pain due to the poor quality of the touch-screen (some finger-presses don’t register until the third or fourth time). Control by app works as well, but there’s a marked delay between changing the temperature on the app and the thermostat actually updating, sometimes as much as five minutes. That’s not an issue when I’m away, but when I’m at home, I’d expect changes to be instantaneous — something that is quite doable as competitors have shown. Honeywell however chose the path of least resistance and has all communication go through their cloud, rather than allowing direct control on the local network.The biggest issue however is that we’re now putting a small computer on the wall to control our HVAC, but other than a pretty (yet useless) screen, we get nothing extra: No accounting for energy usage, run-times, no cool-to-dry option, no energy saving options or suggestions, no more than four set-periods per day, nothing. It’s an overpriced thermostat with limited remote access ability and a free weather app.Conclusion: If you’re in the market for a Honeywell Wifi Thermostat, go for one of the less expensive models. Yes, the screen is pretty, whiz-bang and all that, but Honeywell forgot to make use of it. Or consider the other equally priced options, like the Filtrete/Homewerks-branded ones from RadioThermostat, or even the ecobee, which does extensive logging.This one is going back.

Nice
Had to re-wire the furnace and outside A/C unit even tho they had the C wire
